  • download html source android?

    - by mars
    I'm trying to download a website source code and display it in a textbox but I seem to get an error and can't figure it out :s public void getHtml() throws ClientProtocolException, IOException { HttpClient httpClient = new DefaultHttpClient(); HttpContext localContext = new BasicHttpContext(); HttpGet httpGet = new HttpGet("http://www.spartanjava.com"); HttpResponse response = httpClient.execute(httpGet, localContext); String result = ""; BufferedReader reader = new BufferedReader( new InputStreamReader( response.getEntity().getContent() ) ); String line = null; while ((line = reader.readLine()) != null){ result += line + "\n"; Toast.makeText(activity.this, line.toString(), Toast.LENGTH_LONG).show(); } } how come this doesn't work and throw an IOException?

  • Javascript: Retrieve Object Property Names

    - by Jason
    I'm trying to write a function that needs to know the property names of an object being passed in, like so: var data = { "key1":"value1", "key2":"value2", etc} ^ i want the string value "key1" How do I retrieve the string "key1" from data? I know I can set a property dynamically like data[prop]=value but i want to know what prop is from an object passed in. If that doesn't make sense I suppose I could try to explain more. Thanks! I eventually want to do something like: for (var i = 0; i<data.length; i++) { var name = data[i].getPropertyName() <--- not a real function // do stuff }

  • When open-sourcing a live Rails app, is it dangerous to leave the session key secret in source contr

    - by rspeicher
    I've got a Rails app that's been running live for some time, and I'm planning to open source it in the near future. I'm wondering how dangerous it is to leave the session key store secret in source control while the app is live. If it's dangerous, how do people usually handle this problem? I'd guess that it's easiest to just move the string to a text file that's ignored by the SCM, and read it in later. Just for clarity, I'm talking about this: # Your secret key for verifying cookie session data integrity. # If you change this key, all old sessions will become invalid! # Make sure the secret is at least 30 characters and all random, # no regular words or you'll be exposed to dictionary attacks. ActionController::Base.session = { :key => '_application_session', :secret => '(long, unique string)' } And while we're on the subject, is there anything else in a default Rails app that should be protected when open sourcing a live app?

  • Isses using function with variadic arguments

    - by Sausages
    I'm trying to write a logging function and have tried several different attempts at dealing with the variadic arguments, but am having problems with all of them. Here's the latest: - (void) log:(NSString *)format, ... { if (self.loggingEnabled) { va_list vl; va_start(vl, format); NSString* str = [[NSString alloc] initWithFormat:format arguments:vl]; va_end(vl); NSLog(format); } } If I call this like this: [self log:@"I like: %@", @"sausages"]; Then I get an EXC_BAD_ACCESS at the NSLog line (there's also a compiler warning that the format string is not a string literal). However if in XCode's console I do "po str" it displays "I like: sausages" so str seems ok.

  • I am getting duplicates in UITableView, cellForRowAtIndexPath

    - by Martol1ni
    I am getting duplicates of my array, and wrongly displayed cells in this method: Here I am initializing the array, and adding it to the tableView: NSArray *sectionsArray = [NSArray arrayWithObjects: @"Location", @"Front Post", @"Front Fixing", @"Front Footplate", @"Rear Post", @"Read Fixing", @"Rear Footplate", @"Horizontal Bracing", @"Diagonal Bracing", @"Front Beam", @"Front Lock", @"Rear Beam", @"Rear Lock", @"Guard", @"Accessories", @"Comments", @"Off load ref", @"Loc Empty", @"Loc Affected", nil]; [_tableArray setObject:sectionsArray atIndexedSubscript:2]; [_tableView reloadData]; For some weird reason there are always the 4th object that is messed up, and is either duplicated, or do not have the views from IB. Here is the cellForRowAtIndexPath: method: - (UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell; if (indexPath.section == 2) { cell = [tableView dequeueReusableCellWithIdentifier:@"EntryCell"]; cell.tag = indexPath.row; UILabel *label = (UILabel *)[cell viewWithTag:3]; [label setText:[[_tableArray objectAtIndex:2] objectAtIndex:indexPath.row]]; } return cell; } I have logged the string [[_tableArray objectAtIndex:2] objectAtIndex:indexPath.row], and it logs the right string.

  • what to use in place of std::map::emplace?

    - by kfmfe04
    For containers such as std::map< std::string, std::unique_ptr< Foo >>, it looks like emplace() has yet to be implemented in stdc++ as of gcc 4.7.2. Unfortunately, I can't store Foo directly by value as it is an abstract super-class. As a simple, but inefficient, place-holder, I've just been using std::map< std::string, Foo* > in conjunction with a std::vector< std::unique_ptr< Foo >> for garbage collection. Do you have a interim solution that is more efficient and more easily replaced once emplace() is available?

  • How to find out how namespace got polluted?

    - by dehmann
    Consider the following little piece of code: // all of these include other headers, lots of code: #include "myheader1.h" #include "myheader2.h" #include <string> void foo() { string s("hello world"); // oh no, why does this compile?? } This compiles, so obviously some of the recursively included header files has a using namespace std; somewhere. How would you go about finding out where that offending line of code is? Just using grep on all header files won't really work because that statement is often used inside a function, where it is safe and won't pollute the rest of the code.

  • javascript - Google Chrome cluttering Array generated from .split()

    - by patrick
    Given the following string: var str = "one,two,three"; If I split the string on the commas, I normally get an array, as expected: var arr = str.split(/\s*,\s*/); Trouble is that in Google Chrome (for Mac), it appends extra properties to the array. Output from Chrome's debugger: arr: Array 0: one 1: two 2: three constructor: function Array() index: undefined input: undefined length: 3 So if I iterate over the array with a for/in loop, it iterates over the new properties. Specifically the input and index properties. Using hasOwnProperty doesn't seem to help. A fix would be to do a for loop based on the length of the Array. Still I'm wondering if anyone has insight into why Chrome behaves this way. Firefox and Safari don't have this issue.

  • How to do hex8 encoding in c?

    - by Tech163
    I am trying to encode a string in hex8 using c. The script I have right now is: int hex8 (char str) { str = printf("%x", str); if(strlen(str) == 1) { return printf("%s", "0", str); } else { return str; } } In this function, I will need to add a 0 ahead of the string if the length is less than 1. I don't know why I'm getting: passing argument 1 of 'strlen' makes pointer from integer without a cast Does anyone know why?

  • NullPointerException while trying to bind at SimpleCursorAdapter

    - by hrskrs
    I have asked a question before where i found my mistake. However now i am facing with another problem. I have checked all the similar errors asked on StackOverflow but without success.Any help is appriciated. The idea here is that i am getting image names from DB so depending on those names images from Drawable folder will be shown in a listView together with a description but im getting an error of NullPointException at setViewValue. Here is the code snippet: private void populateListView() { ListView customListView = (ListView)findViewById(R.id.lvCustom); Cursor cursor = DBhelper.getAllimages(); startManagingCursor(cursor); String[] from = { DBhelper.COLUMN_PIC_URL, DBhelper.COLUMN_PIC_DESC}; int[] to = {R.id.ivImg, R.id.tvTitle}; SimpleCursorAdapter cursorAdapter = new SimpleCursorAdapter(this, R.layout.custom_listview_row, cursor, from, to, 0); cursorAdapter.setViewBinder(new ViewBinder() { @Override public boolean setViewValue(View view, Cursor cursor, int columnIndex) { ImageView imageImageView = (ImageView)findViewById(R.id.ivImg); String[] imgNames = new String[cursor.getCount()]; int[] imgResourceIds = new int[cursor.getCount()]; for(int i=0; i<cursor.getCount(); i++){ imgNames[i] = cursor.getString(cursor.getColumnIndex(DBhelper.COLUMN_PIC_URL)); imgResourceIds[i] = getResources().getIdentifier(imgNames[i], "drawable", getPackageName()); imageImageView.setImageResource(imgResourceIds[i]); cursor.moveToNext(); } return true; } }); customListView.setAdapter(cursorAdapter); } Here is the Error from LogCat: I have tried to log the output of imgNames[i] where it returns the url pic from the DB correctly and imgResourceIds[i] where it return the image resource id correctly also(it does not return NULL but something like: 295731). But it stops at imageImageView.setImageResource(imgResourceIds[i]); To see from where that NullPointerException is coming, i commented out imageImageView.setImageResource(imgResourceIds[i]);. This time imageNames(those with a TAG) and imgResourceIds(those system printed out) came correctly but doubled, when i removed cursor.MoveToNext() last row were doubled. Here is the screen shot of that: I have tried all the suggestions on stack about gettin a NullException but without success. Any idea where i am doing mistake?

  • Excel Interop: Fastest way to change color of portions of text in a huge range of cells

    - by Kyopaxa
    There some articles about the fastest way to write data using Excel interop assigning directly an Array of data to the value of the range. Like: string[,] multidimensionalArrayData = new string[200, 3]; // (...) Fill multidimensionalArrayData with your data dataSheet.Range["A1:C200"].Value = multidimensionalArrayData; There are also some articles about how to change the Font color of a specific portion of text, for example (VB this time): With ActiveCell.Characters(Start:=3, Length:=3).Font .Name = "Arial" .FontStyle = "Regular" .Size = 10 .Color = "Red" .ThemeFont = xlThemeFontNone End With The question now is, what would be the fastest way to change the color of specific portions of text for thousands of cells? Currently, in my C# code, I have to do it cell by cell, with a horrible performance hit. Is there a way to fill an array of 'Characters' objects in C# and pass that array to a range in one go? Any other solutions?

  • In .NET, how can I convert from "0.000" to a 'long'?

    - by willem
    I have a string, "0.000" (or any similar string), that I would like to convert to a long. I am happy to "chop-off" anything after the decimal. What is the best way to go about this? I can convert to double and then to long, but I'm just wondering if there is an easier way. All the following statements throw exceptions: long l3 = Convert.ToInt64(nrToConvert); long l1; long.TryParse(nrToConvert, out l1); long l2 = long.Parse(nrToConvert);

  • Default http/admin port in dropwizard project

    - by mithrandir
    I have a dropwizard project and I have maintained a config.yml file at the ROOT of the project (basically at the same level as pom.xml). Here I have specified the HTTP port to be used as follows: http: port:9090 adminPort:9091 I have the following code in my TestService.java file public class TestService extends Service<TestConfiguration> { @Override public void initialize(Bootstrap<TestConfiguration> bootstrap) { bootstrap.setName("test"); } @Override public void run(TestConfiguration config, Environment env) throws Exception { // initialize some resources here.. } public static void main(String[] args) throws Exception { new TestService().run(new String[] { "server" }); } } I expect the config.yml file to be used to determine the HTTP port. However the app always seems to start with the default ports 8080 and 8081. Also note that I am running this from eclipse. Any insights as to what am I doing wrong here ?

  • Load custom class properly

    - by LinusAn
    I have a custom class which I want to "load" inside the firstViewController and then access it from other classes by segues. My Problem is, I can't even access and change the instance variable inside the firstViewController. Somehow I'm "loading" it wrong. Here is the code I used until now: inside viewController.h @property (strong, nonatomic) myClass *newClass; inside viewController.m @synthesize newClass; I then try to access it by: self.newClass.string = @"myString"; if(newClass.string == @"myString"){ NSLog(@"didn't work"); } Well, I get "didn't work". Why is that? When I write myClass *newClass = [myClass new]; It does work. But the class and its properties gets overwritten every time the ViewController loads again. What would you recommend? Thank you very much.

  • return not breaking loop (c#)

    I'm trying to determine if a user is a member of a group or not in AD. However, the following doesn't seem to be working for some reason... public bool MemberOf(string sObjectName, string sGroup, bool bIsGroup) { DirectoryEntry dEntry = CreateDirectoryEntry(); DirectorySearcher dSearcher = new DirectorySearcher(dEntry); if (bIsGroup) dSearcher.Filter = "(distinguishedName=" + sObjectName + ")"; else dSearcher.Filter = "(&(sAMAccountName=" + sObjectName + ")(objectClass=user))"; SearchResult sResult = dSearcher.FindOne(); if (sResult != null) { foreach (object oGroup in sResult.Properties["MemberOf"]) { if (oGroup.ToString() == sGroup) return true; else this.MemberOf(oGroup.ToString(), sGroup, true); } } return false; } Another variation: http://users.business.uconn.edu/dwick/work/wtf/6-14-2010%201-15-15%20PM.png Doesn't work either. This seems like a really dumb question... but shouldn't it break the loop upon "return true;"

The class A has to be loaded and instantiated first. But my question is: if it's done in context of the thread T, or rather in context of some other (special) "classloader" thread?
